Insecticide Resistance

Insecticide resistance occurs when insects evolve over time to survive exposure to chemicals designed to kill them. When an insect population is repeatedly treated with the same insecticide, some insects may naturally have or develop traits that protect them. These resistant insects survive and reproduce, passing on their resistant traits to future generations. Over time, the majority of the population becomes less affected by the insecticide, making it harder to control pests. This process complicates pest management and requires strategies like rotating chemicals or using integrated approaches to maintain effectiveness.
